The subsidy scheme for solar water heaters was ended in February 2011. Commercial businesses can still benefit from the tax-reduction for energy investments (EIA), which comes to about 15% of the investment costs.
A new support scheme is the SDE+. This is a feed-inn tariff that has been expanded to include large (>100 m2) solar heating systems. The feed-inn tariff works with a tender system. The tariff is between €0 and €20 per Gj produced useful heat.
For solar buildings the main incentive is the building regulation and local climate policies.
